In the wake of Bermane Stiverne's upset of Chris Arreola in a WBC heavyweight elimination bout, Vitali Klitschko has confirmed his willingness to defend the WBC heavyweight championship against Stiverne. Klitschko, the 41 year old brother of Wladimir Klitschko has held the WBC title from 2004-2005 and 2008 through the present. He did not lose the title in the ring, but was retired from 2005-2008. Until this announcement, it was not clear if Vitali would continue boxing or pursue a career in Ukrainian politics. source: wbc
